Olaf_ZG Posted October 18, 2022 Share #1  Posted October 18, 2022 Advertisement (gone after registration) I have an old 50mm cron, v2/v3 depending which wiki.  My filterring got stuck, and when I try to untie it, the part where one is setting the aperture is turning as well. I guess that is not good. the lens still focus, but I am a bit worried, did I damage my lens? Link to post Share on other sites More sharing options...

rtai Posted October 18, 2022 Share #2  Posted October 18, 2022 If it’s a v2 the one after the v1 which was the collapsible then the front part is supposed to unscrew. Just screw it’s back in but don’t torque it. 1 Link to post Share on other sites More sharing options...
